Pilot Test of Deep Coalbed Methane Full Gas Power Generation Full Electric Drive Fracturing

Abstract In order to solve the configuration technology of fracturing equipment in deep coalbed methane reservoir construction, taking the electric fracturing equipment of deep coalbed methane in Linxing-Shenfu block as an example, the integrated configuration method of deep coalbed methane electric fracturing equipment is put forward according to the requirements of fracturing construction and the operation capacity of the equipment. Specific configuration requirements are put forward from fracturing pump unit, Power transmission and distribution system, Variable frequency room and variable frequency technology, sand transport device, sand mixing device, liquid supply system, high and low pressure manifold system and instrument control center, other equipment, which are applied in Shenfu LGPC2-10 site. The application results show that the proposed method can meet the requirements of high pressure, large discharge, high sand ratio, large sand volume and 24 hours operation time. Under the condition of meeting the power reserve coefficient of 1.3 for the pump unit, the power redundancy coefficient is 1.38 ; the output grid power of gas power generation is 19 200 kW, which is greater than the power consumption terminal of 18 800 kW; the fracturing sand storage tank meets the construction requirements of 600 m 3 of the sixth section of well 11H with the maximum sand volume in a single section; the electric sand mixing skid meets the sand adding requirement of 26% of the maximum sand ratio; and realize green and low-carbon development. The research results can lay the equipment foundation for large-scale electric fracturing of deep coalbed methane, and have certain reference significance for the subsequent large-scale promotion.
